Description
From user MB:
It might also be good to know why they entered the PSG screening stage and what the exclusion criteria was. Regarding the former, tonsil size and/or parental reports of frequent snoring appears to have been an important condition (According to the NEJM paper supplement)?! Regarding the latter, an OMAHI3 value outside the eligibility range appears to be quite common. It would be very helpful to have some data on those points?!
